The Harrington Mini-Cat AH manipulator model with hook mount is an air-powered hoist with a one-hand control for left- or right-handed operation, low headroom design, and unlimited duty cycle for continuous operation in high-volume production environments. It has a spring-loaded, eight-vane motor to facilitate air feathering control for precise load handling and gentle load placement. This hoist has an average decibel rating (dBA) of 80dBA, measured at a distance of three feet from the exhaust manifold, for comfortable noise levels. It also has an aluminum valve section and a nickel plated load chain for resistance to corrosion, abrasion, and wear. The Harrington Mini-Cat AH air hoist is typically used in high-production manufacturing or construction environments that require continuous operation in areas such as assembly lines or workstations, but also may be used for similar applications in other industries. This hoist is produced to comply with American Society for Mechanical Engineers (ASME) B30.16 and ASME HST-5M standards. When used according to manufacturer’s recommendations, this product is covered by a one-year warranty from date of shipment against defects in workmanship or materials.
Hoists are devices that use relatively small amounts of force to lift, lower, and move heavy loads. Air hoists, also called pneumatic hoists, are powered by compressed air to transfer a small, motor-generated force across a series of gears that multiply the force into one large enough to lift the designated load. The load is usually lifted by a hook that is attached to a chain, rope, or wire. Air hoist are commonly suspended from structures by hook or trolley mounts. They are typically used in a variety of industries such as transportation, construction, manufacturing, mining, and material handling for heavy-duty applications, frequent and repetitive activities, or in hazardous areas where electricity is not advisable.
Load capacity is the maximum rated load a hoist can handle. While manufacturers may indicate they have tested a hoist beyond its limits, operators should never attempt to lift a load heavier than the maximum rated load. Lifting speed describes, in feet per minute (fpm), how quickly the hoist can lift the maximum rated load. Lift is the maximum vertical distance the load hook can move a load. Headroom is the distance from the bottom of the load hook to the top of the hoist. This is the minimum amount of vertical space needed for the hoist to hang freely and operate correctly. Duty ratings describe the maximum amount of time a hoist can run and the number of times it can start over a given time period under various conditions such as intermittent use, or short and lengthy periods of operation.
Harrington Hoists manufactures hoists and cranes. The company, founded in 1854 and headquartered in Manheim, PA, meets International Organization for Standardization (ISO) standard 9001.
